6 Claims. (Cl. 229-23) The main objects of this invention are: A

First, to provide a container that is grease and moisture proof, welladapted for peanut butter, lard and the like.-

Second, to provide a container of this character consisting of twocomplete wall units nested closely or fitting one within the other andhaving an interlining disposed between the wall units which is greaseand moisture proof.

Third, to provide improved cover retaining means.

Fourth, to provide a container having the above desirable features,which is simple and economical in its parts and eiiicient for thepurpose intended.

Objects relating to details and economies of my invention willappearfrom the description to follow. The invention is defined and pointed outin the claims.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawing, in which:

Fig. i is aperspectiveyiew oi a closed con-V tainer embodying thefeatures of my invention.

Fig. 2 is a perspective view of the blank for the outer carton or outerwall unit.

Fig. 3 is a perspective view of the blank for the inner wall unit.

Fig. e' is a perspective view of the cover.

Fig. 5 is a perspective view of the inner wall unit.

Fig. 6 is an enlarged fragmentary vertical section on a linecorresponding to line 6-6 of Fig. l.

Fig. '7 is an enlarged fragmentary perspective view, portions beingbroken away and shown in vertical section.

Referring to the drawing, l is a container having downwardly taperedside walls and an insert cover 2. The container 1 is formed of an outerwall .unit 3 and an inner wall unit or lining e nested closely together,or with the inner carton fitting within the outer carton, there being a(grease prooi interlining 5 of metal foil, Cellophane or the likedisposed between the wall units. Thus arranged, the double-walledcontainer 1 is grease and moisture proof, the inner and outer wall unitsbeing preferably formed of stin` paper, or cardboard.

The cuter wah unit 3 is made up from a blank, (Fig. 2l consisting ofabottom 6 having a pair ci flaps i at opposite sides thereof and sidewalls 9 connected thereto along hinged lines. Connected to the sidewalls 8 along hinged lines are flaps or plies 9 and 10, respectively,which are Y overlapped with the iiaps 7 therebetween to form two-ply,side walls. The innerplies 9 of the twoply side walls of the outer wallunit are provided with horizontal slots 11 arranged in spaced parallelrelation to the top of the container.

The inner wall unit or lining 5 is similarly 0' made up of a blank (Fig.3) consisting of a bottom 12 having aps 13 at opposite sides thereof andside walls 14 connected thereto along hinged lines. The plies 15 and 16,respectively, are connected to theside walls 14 along hinged lines 55and are adapted to be overlapped with the naps 13 therebetween to formthe two-ply side walls of the inner wall unit. The upper edges or tops17 of the inner plies 15 terminate in spaced relation tothe top ofy thecontainer. Flaps 18 are 70 connected to the side walls 14 along thehinged lines 19, while the hinged flaps 20 are connected to the outerplies 16 along the hinged lines 21. The inner wall unit is set up in themanner illustrated by Fig. 5 andthe naps 20 are folded 75 over the tops1'7 of the inner plies 15. The aps 18 are folded inwardly and coact withthe flaps 20 to provide a cover supporting shoulder or ledge on whichthe cover 2 is adapted to rest.

The inner and outer wall units are set up and nested together with thegrease proof interlining disposed therebetween, as illustrated by Figs.6

'and 7. The cover 2 is inserted within the upperv -of the cover sidewalls are provided with slits 23 forming outwardly projecting tongues 2dwhich are adapted to coact with the slots 11 to lock the 99 cover inposition within the container. The container thus formed is grease andmoisture proof and is very strong and rugged. The filled containers maybe stacked in superimposed relation without fear of the coverscollapsing due to the 95 weight of the cartons thereabove. This resultsfrom the cover supporting shoulder formed by the inturned flaps of theinner wall member.

The completed containerA is very rigid and resists collapsing to amarked degree. It also lo@ possesses the desirable characteristics ofbeing grease and moisture proof.

1 have illustrated and described my improve-- ments in embodiments whichI have foundvery practical. I have not attempted to illustrate or, 05describe other embodiments or adaptations, as it is believed thisdisclosure will enable those skilled in the art to embody or adapt myimprovements as may be desired.

Having thus described my invention, whatI u@ claim as new and desire tosecure by Letters Patent, is:

1. A double wall container comprising a downwardly tapered outer wallunit having opposed side walls comprising overlapping plies, the innerplies having horizontal slots spaced from the upper edge thereof, adownwardly tapered inner wall unit nested within said outer wall unitand having opposed side walls comprising overlapping plies, the two-plyside walls of said inner wall unit being disposed to overlap the singleply walls of the outer wall unit, the inner plies of the inner wall unittwo-ply side walls terminating in spaced relation to the top of thecontainer, the outer plies having flaps bent inwardly over the upperedges of said inner plies and coacting with similarly inwardly bentflaps on the single ply side walls to provide a. cover supporting ledge,and a cover disposed within the outer wall unit to rest upon said coversupporting ledge of the inner wall unit and having upstanding sidewalls; a pair of the said cover side walls being slitted to provideoutwardly projecting tongues coacting with said slots to retain thecover in position.

2. A double wall container comprising a downwardly tapered outer wallunit having opposed side walls comprising overlapping plies, adownwardly tapered inner wall unit nested within said outer wall unitand having opposed side walls comprising overlapping plies, the two-plyside walls of said inner 4wall unit being disposed to overlap the singleply walls of the outer wall unit, the inner plies of the inner wall unittwoply side walls terminating in spaced relation to the top of thecontainer, the outer plies having flaps bent inwardly over the upperedges of said inner plies and coacting with similarly inwardly bent apsonthe single ply side walls to provide a cover supporting ledge, and acover disposed within the outer wall unit to rest upon said coversupporting ledge of the inner wall unit.

Leeaie 3. A double wall container comprising a downwardly tapered outerwall unit having opposed side walls comprising overlapping plies, theinner plies having horizontal slots spaced from the upper edge thereof,a downwardly tapered inner wall unit nested within said outer wall unitand having inwardly bent cover supporting flaps, and a cover disposedwithin the outer wall unit to rest upon said cover supporting iiap ofthe inner wall unit and having tongues coacting with said slots toretain the cover in position.

4. A double wall container comprising a downwardly tapered outer wallunit having opposed side walls comprising overlapping plies, the innerplies having horizontal slots spaced from the upper edge thereof, adownwardly tapered inner wal'l unit nested within said outer wall unitwith its upper edge spaced from the top thereof, and a cover disposedwithin the outer wall u nit to rest upon said inner wall unit and havingtongues coacting with said slots to retain the cover in position.

5. A container comprising an outer complete box-like wall unit of fiberboard, an inner complete. box-like wall unit of fiber board nestedwithin said outer wall unit and having inturned aps on its wallsproviding cover supporting ledges placed from the top of the outer wallunit, a
